兩個集合set1和set2的對稱差是元素集合，它們在集合set1或set2中的一個中但不在兩個集合中。
用法:
set1_name.symmetric_difference(set2_name)
參數：
它隻需要一個集合作為參數。如果傳遞了列表，元組或字典，則將其轉換為集合並執行任務。
返回值：
Returns a set which is the symmetric difference between the two sets.
symmetric_difference()的工作代碼：
# Python program to demonstrate the use of
# of symmetric_difference() method
list1 = [1, 2, 3]
list2 = [2, 3, 4]
list3 = [3, 4, 5]
# Convert list to sets
set1 = set(list1)
set2 = set(list2)
# Prints the symmetric difference when
# set is passed as a parameter
print(set1.symmetric_difference(set2))
# Prints the symmetric difference when list is
# passed as a parameter by converting it to a set
print(set2.symmetric_difference(list3))輸出：
{1, 4}
{2, 5}
